Change BaudRate in a OpenAt program

Hi.

I like to change the baud rate in my OpenAt program program (9600 and 115200) at UART1.

Im using the next command:

adl_atCmdCreate(“AT+IPR=9600”,ADL_AT_PORT_TYPE( ADL_AT_UART1, FALSE ),Res_Baud_Handler,"*",NULL);

but neither in my program, and neither after the end of my program, the baud rate still 115200!

After my program:

at+ipr?
+IPR: 9600

(in 115200 baud)

and if i write the AT+IPR=9600 (in HyperTerminal), the modem change the baud rate in 9600.

(mysytem: Q2406B, AT v03.02)

Any idea ?

ok.

Must close the uart1 before IPR command

adl_atCmdCreate(“AT+WMFM=0,0,1”,ADL_AT_PORT_TYPE( ADL_AT_UART1, FALSE ),Res_Handler1,"*",NULL);

adl_atCmdCreate(“AT+IPR=9600”,ADL_AT_PORT_TYPE( ADL_AT_UART1, FALSE ),Res_Handler2,"*",NULL);

adl_atCmdCreate(“AT+WMFM=0,1,1”,ADL_AT_PORT_TYPE( ADL_AT_UART1, FALSE ),Res_Handler3,"*",NULL);

im

I have the same problem. But when I’m trying to send “AT+WMFM” command modem responds with “+CME ERROR: 3” (Operation not allowed). What should I do to fix it?
